The RainFlex® Elite is constructed with a new 4-way stretch, knit fabric that was initially tested in rainy, humid SE Asian countries. Previous versions of RainFlex had an 8K/8K waterproof/breathable rating, while the new RainFlex Elite has a 15K/15K rating. Like original RainFlex, the Elite is distinguished by its quietness, 4-way stretch and overall comfort when playing.
